Count me in when the new batch arrives! I've got some troubleshooting to do  >:(
There's nothing like the right tool for the job.

Finished mine, all perfect, thanks a lot, really handy tool !

One small thingy in the bom 1.0:
Position 11 calls for 2 SPDT switches, but you need only one !

So you need a second PCB for the extra switch, right?  ;D

Just kidding. Thanks for reporting the bug. I uploaded a corrected version of the BOM.

Cheers

No problem. I still have about five boards in stock and probably gonna reorder a batch for future demand.

Just PM me your PayPal adress and I will send you an invoice in return.

If anybody needs an adapter for testing LAWO 325 DOAs let me know.

Looks nice, Volker. But you really need to add some stand-offs to the test jig  :o ;D ;)
By the way, thanks for mentioning my board on your Instagram feed!

Happy New Year to all!

Thanks Carsten. The test jig I mostly use does indeed have stand-offs

Hello.

As a good all around soldering guy and builder. Can someone explain the process of using this PCB to test opamps and what to look for? Im just starting into opamps and want them all to be tip top. Just not 100% sure what Id be looking for. I have two good meters but what is needed for signal generation?

Thanks!

Hi Blackdawg,

maybe some of your questions have already been answered in my thread over at the Lab: https://groupdiy.com/index.php?topic=60489.0

But basically, the PCB will help you to test both 2520 and Neumann type DOAs. These tests might be a basic burn-in without the risk of damaging any other expensive circuitry or further signal analysis. For this purpose it can either be connected to a signal generator and a scope or to a computer sound card.

The jig features four different gain settings and has two switchable loads for the DOA.

Cheers,
Carsten
